A stretching-in type cutting and film taking device for sheet metal part machining

Abstract

This utility model discloses an insertable cutting and film-removing device for sheet metal processing, comprising: a sheet metal body with holes; an upper cutting assembly, wherein support rods are fixedly inserted at equal intervals around the bottom surface of a base, and a guide rod is inserted through the top surface of the base; and a lower cutting assembly located below the upper cutting assembly. This utility model moves a moving stage to the upper surface of the holes on the sheet metal part, driving a rotating gear ring to rotate and causing the upper needle rod to make circular cuttings around the holes. This allows the cylindrical block and the hollow frame structure to extend into the inner cavity of the holes, driving a connecting rod structure to cause a flipping plate to flip outwards within the hole cavity. During subsequent withdrawal, a downward negative pressure is generated on the inner surface of the flipping plate, adsorbing and simultaneously removing the previously cut film from the upper surface of the holes. The cutting and film-removing operation of the film on the upper and lower surfaces of the holes can be completed in the same direction on the sheet metal part, saving processing steps and improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an insert-type cutting and film-taking device for sheet metal processing. Background Technology

[0002] Sheet metal parts refer to plates with one type of metal clad on top of another, achieving resource conservation and cost reduction without compromising performance. Composite methods typically include explosive lamination, explosive rolling lamination, and rolling lamination. Composite materials can be classified by appearance into composite plates, composite pipes, and composite rods. They are mainly used in corrosion protection, pressure vessel manufacturing, power construction, petrochemical, pharmaceutical, light industry, and automotive industries.

[0003] After sheet metal parts are processed and formed, a protective film is sometimes required to be applied to their surface. If the sheet metal parts need to have holes made on their surface to meet usage requirements, the film should be applied around the holes. However, the protective film should be cut at the corresponding positions before applying the film, and the hole positions need to be accurately measured in advance. Otherwise, the protective film application position at the holes may be deviated, which increases the processing steps and reduces production efficiency. If the film is cut after the sheet metal parts are coated, the current equipment cannot cut and remove the film from both sides of the holes in the same direction because the sheet metal parts need to be coated on both sides. Therefore, we propose an insertable cutting and film removal device for sheet metal parts processing. Utility Model Content

[0004] The purpose of this utility model is to provide an insertable cutting and film-taking device for sheet metal processing, so as to solve the problems mentioned in the background art.
